The present invention provides an organic compound which is easy to synthesize, is excellent in chemical stability, has semiconductor characteristics (high carrier mobility), and has high solubility in a solvent. The present invention is a compound represented by the formula (1) or the formula (2). □□[In the formula (1), X is oxygen, sulfur or selenium; n is 0 or 1; R1 to R3 are hydrogen, fluorine, alkyl having 1 to 20 carbon atoms, aryl, pyridyl, furyl, thiophene The group or the thiazolyl group or the like, except that in the case where X is selenium, all of R1 to R3 are not hydrogen at the same time, and X is sulfur and all of R1 are butyl at the same time. In the formula (2), X is oxygen, sulfur or selenium; n is 0 or 1; R1 to R2 are hydrogen, an alkyl group having 1 to 20 carbon atoms, an aryl group, a pyridyl group, a furyl group, a thienyl group or a thiazolyl group. Wherein, all of R1 to R2 are hydrogen at the same time. ] |
